High Speed, High Feed Rate • The special ground insert and rigid holder design facilitate high performance speed and feed rates. For example, drilling alloy steel at 6000 rpm and feed rate of 600 mm/min. (0.1 mm/rev.)

Easy Tool Length Setting • The axial position accuracy of the insert is 0.05 mm (.002”). It is not necessary to reset the tool length when changing the insert or cutting edge.

Extended Tool Life

Special forms are possible

• Coolant can be supplied through the center of the holder to increase performance and extend tool life.• Insert geometry, grades and coating process are specifically engineered for centering applications.

Excellent Repeatability• The positioning repeatability of the insert is within 0.02 mm (.0008”) in radial direction, thus ensuring conformity to any national standards.

World’s first indexable center drillShortens set up and center drilling timeIncreases tool life and reduces tooling costs

The “ i-Center ” is a trademark of Nine9,the developer of the first indexable center drill in the world.(Patented)Offering an indexable insert system for the 1st time, Nine9’s “i-Center ” designimproves your process performance.

High pressure coolant can be supplied through center directly to tip of center drill insert.

High pressure coolant can be supplied through center directly to tip of center drill insert.
